ThreadBack AI v1.2.0 — Local AI Intent Engine

AI-first local semantic intent clustering with bundled BGE-small-en-v1.5 INT8. Every new semantic assignment is evaluated on-device from bounded metadata. No API key, backend, remote AI or telemetry.

Uniform candidate ranking, bounded page/centroid support, stable purpose anchors and multi-page workflow reconciliation improve continuity. Singleton and uncertain pages remain latent until supported. A durable pending-event queue preserves intent memory through MV3 worker termination.

Verified: final automated suite, packaging/security checks and actual unpacked Chromium workflows, including offline model loading, arbitrary-topic grouping, Resume, manual controls and browser restart. Worker interruption lost 0 events and duplicated 0.

Limitations: embedding similarity is not calibrated probability or proof of user purpose. Closely related goals may merge and ambiguous pages may split/remain latent. Installed Chrome/Edge distributions and exact RAM usage were not separately qualified.
